[RESOLVED] Convert Bytes into bits

[Half]

Hi all, I am trying to show / see the binary code of a file. So far I have this:

Dim fStrm As FileStream
        Dim bytes(9) As Byte
 
 
        fStrm = New FileStream("c:\test.gif", FileMode.Open, FileAccess.Read)
        fStrm.Read(bytes, 0, bytes.Length)
 
        Dim i As Integer
        For i = 0 To bytes.Length - 1
            RichTextBox2.Text += bytes(i).ToString & vbCrLf
        Next

This gives me
71
73
70
56
55
97
253
0
77
0
which I suppose are bytes. What is the logic interpreting the bytes as a range 0 through 255? How to make them 000101010s etc?
